Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

A dust collection container 1 according to an embodiment of the present invention will be described below with reference to fig. 1 to 17, and the dust collection container 1 may be used in a sweeping robot 100.

The dust collecting container 1 according to an embodiment of the present invention includes: housing 11, filter assembly 12, pressure plate 13, and drive mechanism 14.

Wherein, the housing 11 may be provided therein with an accommodating space, the filter assembly 12 may be provided in the accommodating space, the filter assembly 12 may cooperate with the housing 11 to divide the accommodating space into a dust collecting chamber 11a and an exhaust chamber 11b, the housing 11 may be provided thereon with an air inlet 11c communicating with the dust collecting chamber 11a and an air outlet 11d communicating with the exhaust chamber 11b, and the dust collecting chamber 11a may be provided with a dust outlet 11 e.

Specifically, when the dust collecting container 1 is operated, an air flow containing dust and foreign substances may enter the dust collecting chamber 11a through the air inlet 11c, and the air flow may flow from the dust collecting chamber 11a to the air discharge chamber 11 b. When the air flow passes through the filter assembly 12, the filter assembly 12 may filter out dust and foreign substances in the air flow, the dust and foreign substances may be stored in the dust collection chamber 11a, and the filtered air flow may enter the exhaust chamber 11b and be discharged through the air outlet 11 d. When it is necessary to clean the dust in the dust collection chamber 11a, the dust outlet 11e may be opened to dump the dust in the dust collection chamber 11 a. Alternatively, the exhaust chamber 11b and the dust collecting chamber 11a may be spaced in the up-down direction, and thus, the filtered dust and foreign substances may fall into the dust collecting chamber 11a by gravity, and the filtering effect of the filter assembly 12 may be improved.

As shown in fig. 1-2, a drive mechanism 14 may be coupled to the pressure plate 13 such that the pressure plate 13 is reciprocatably disposed within the dust collection chamber 11a between an ash pressing position and an initial position. When the pressing plate 13 moves toward the dust pressing position, the pressing plate 13 may cooperate with the inner circumferential wall of the dust collection chamber 11a to compress the dust. Specifically, when the dust collection container 1 is operated, the pressing plate 13 is in the initial position. When the dust in the dust collecting container 1 is full, the driving mechanism 14 can positively drive the pressing plate 13 to move from the initial position to the dust pressing position, and the pressing plate 13 can compress the dust in the dust collecting chamber 11a during the moving process, so that the dust can be compacted, and the occupied space of the dust can be reduced. When the platen 13 is moved to the ash pressing position, the driving mechanism 14 may reversely drive the platen 13 to move the platen 13 to the initial position, whereby one ash pressing cycle may be completed.

It can be understood that the filtered dust and foreign substances can be stored in the dust collecting chamber 11a, and since the dust and foreign substances are in a fluffy state, the dust and foreign substances can quickly occupy the entire dust collecting chamber 11a, thereby reducing the space utilization of the dust collecting chamber 11a and requiring a user to frequently clean the dust in the dust collecting chamber 11 a. The driving mechanism 14 can drive the pressing plate 13 to compress the dust in the dust collecting chamber 11a, so that the dust can be compacted, the occupied space of the dust can be reduced, the dust in the dust collecting chamber 11a does not need to be cleaned frequently, the service cycle of the dust collecting container 1 is greatly prolonged, and great convenience is brought to the practical use of a user. Moreover, the driving mechanism 14 can realize the automatic control of the dust collecting container 1, and the operation is convenient.

It should be noted that the initial position of the pressing plate 13 is fixed, the dust pressing position of the pressing plate 13 can be changed, and the dust pressing position can move toward the initial position with the increase of the dust pressing times.

Alternatively, when the pressing plate 13 moves to the dust pressing position, the pressing plate 13 may stay at the dust pressing position for a set time, so that the dust may be subjected to pressure maintaining, and a good dust pressing effect may be achieved. Further, the dwell time of the platen 13 may be 5 seconds.

According to the dust collecting container 1 provided by the embodiment of the invention, by arranging the driving mechanism 14 and the pressing plate 13, the driving mechanism 14 can drive the pressing plate 13 to reciprocate in the dust collecting chamber 11a so as to compress the dust in the dust collecting chamber 11a, therefore, the occupied space of the dust can be reduced, a user does not need to frequently clean the dust in the dust collecting chamber 11a, the service cycle of the dust collecting container 1 is greatly prolonged, and great convenience is brought to the practical use of the user. The dust collecting container 1 has convenient operation, high automation degree and strong practicability.

According to some embodiments of the present invention, the pressure plate 13 may be reciprocally movable between a first direction toward the filter assembly 12 and a second direction away from the filter assembly 12, and the pressure plate 13 may be provided with an exhaust port 131b communicating with the exhaust chamber 11 b. For example, the filter assembly 12 may be located above the dust collection chamber 11a, the pressing plate 13 may be moved in the up-and-down direction, and the initial position of the pressing plate 13 is located above the dust pressing position. When the pressing plate 13 compresses the dust, the pressing plate 13 moves from top to bottom, the dust is gradually transformed from a fluffy state to a compacted state, and air in the dust can enter the exhaust chamber 11b through the exhaust port 131 b. When the dust collecting container 1 is operated, the pressing plate 13 is in the initial position, and the air flow can enter the dust collecting chamber 11a through the air inlet 11c and then enter the filter assembly 12 through the air outlet 131 b. Therefore, through the arrangement, the dust collecting container 1 can be simpler in structural design and more convenient to operate.

It will be understood, of course, that the manner of movement of the platen 13 is not so limited. For example, the filter assembly 12 may be located above the dust collection chamber 11 a. Wherein the pressing plate 13 may reciprocate in the left and right direction to compress the dust, as shown in fig. 1. As shown in fig. 4, the pressing plate 13 may also reciprocate in the front-rear direction to compress the dust. .

For example, the driving mechanism 14 may drive the platen 13 to reciprocate in the up-down direction, a rack 143 extends in the up-down direction, a lower end of the rack 143 is connected to the platen 13, and a gear 142 is located at one side of the rack 143. When the pressing plate 13 moves from the initial position to the ash pressing position, the driving member 141 drives the gear 142 to rotate clockwise, and the gear 142 is engaged with the rack 143 to drive the pressing plate 13 to move downwards. When the pressing plate 13 moves from the dust pressing position to the initial position, the driving member 141 drives the gear 142 to rotate counterclockwise, and the gear 142 is engaged with the rack 143 to drive the pressing plate 13 to move upward.

As shown in fig. 8, the drive mechanism 14 may include a drive member 141, a first drive gear 145, a second drive gear 146, and a threaded post 147, according to some embodiments of the invention. Wherein the driving member 141 may be disposed in the accommodating space, the first transmission gear 145 may be connected to the driving member 141 to be driven by the driving member 141 to rotate, as shown in fig. 12, a fitting hole 146b may be disposed on the second transmission gear 146, a plurality of fitting teeth 146a may be disposed on an outer circumferential edge of the second transmission gear 146 and distributed in a circumferential direction thereof, an inner thread may be disposed on an inner circumferential wall of the fitting hole 146b, the second transmission gear 146 may be engaged with the first transmission gear 145 through the plurality of fitting teeth 146a to be driven to rotate by the first transmission gear 145, the threaded column 147 may extend in a moving direction of the pressing plate 13 and one end of the threaded column 147 is connected to the pressing plate 13, the second transmission gear 146 may be sleeved on the threaded column 147 through the fitting hole 146b, the inner thread may be threadedly engaged with an outer thread on an outer circumferential wall of the threaded column 147 to drive the pressing, therefore, the driving mechanism 14 can be more simply designed and the operation of the pressure plate 13 can be more stable by the above arrangement.

Alternatively, the first transmission gear 145 and the second transmission gear 146 may be spur gears, the first transmission gear 145 and the second transmission gear 146 may also be helical gears, and the first transmission gear 145 and the second transmission gear 146 may also be bevel gears. When the first transmission gear 145 and the second transmission gear 146 are spur gears or helical gears, the rotation axes of the first transmission gear 145 and the second transmission gear 146 are parallel, and the first transmission gear 145 and the second transmission gear 146 are arranged in the horizontal direction. As shown in fig. 8, when the first and second transmission gears 145 and 146 are bevel gears, the rotation axes of the first and second transmission gears 145 and 146 are perpendicular, and the first and second transmission gears 145 and 146 may be arranged in a vertical direction.

As shown in fig. 6-7, in some embodiments of the present invention, the driving mechanism 14 may further include a first bevel gear 148 and a second bevel gear 149, the first bevel gear 148 may be connected to the driving member 141 to be driven by the driving member 141 to rotate, a rotation axis of the second bevel gear 149 is perpendicular to the rotation axis of the first bevel gear 148, the second bevel gear 149 is engaged with the first bevel gear 148, and the second bevel gear 149 may be coaxially disposed with the first transmission gear 145 to drive the first transmission gear 145 to rotate synchronously therewith, so that not only the occupied space of the driving mechanism 14 may be reduced, but also the moving speed of the platen 13 may be conveniently adjusted.

Specifically, as shown in fig. 9, when the driving mechanism 14 drives the platen 13 to move, the driving member 141 can drive the first bevel gear 148 to rotate, and the second bevel gear 149 is engaged with the first bevel gear 148 to be driven to rotate by the first bevel gear 148. As shown in fig. 10 to 11, since the first transmission gear 145 is disposed coaxially with the second bevel gear 149, the first transmission gear 145 can rotate synchronously with the second bevel gear 149. The first transmission gear 145 can be meshed with the second transmission gear 146 to drive the second transmission gear 146 to rotate while rotating, so that the internal thread in the assembly hole 146b is in threaded fit with the external thread on the threaded column 147, and the threaded column 147 can be driven to drive the pressing plate 13 to move. It will be appreciated that the placement of the drive member 141 can be varied by virtue of the fact that the axis of rotation of the second bevel gear 149 is perpendicular to the axis of rotation of the first bevel gear 148. For example, the driving member 141 may be horizontally disposed, so that the space occupied by the driving mechanism 14 in the up-down direction can be reduced.

Alternatively, the driving member 141 may be a stepping motor, and the stepping motor has stable operation and can precisely control the rotation direction and the rotation number of the motor, so that the position accuracy of the pressing plate 13 can be improved, and a good driving effect can be achieved.

It should be noted that the design form of the driving mechanism 14 is not limited to this. For example, the driving member 141 may be a hydraulic cylinder or a linear motor, the driving member 141 may be disposed in the accommodating space, one end of the driving member 141 may be connected to the pressing plate 13, and the driving member 141 may drive the pressing plate 13 to move in a forward direction and a reverse direction, thereby switching the pressing plate 13 between the initial position and the dust pressing position.

The manner of engagement between the opening/closing plate 16 and the housing 11 is not limited to this. For example, the opening and closing plate 16 may also slide relative to the housing 11 to open or close the dust outlet 11 e.

In some embodiments of the present invention, the housing 11 may be provided with a trigger (not shown), the trigger may be connected to the opening/closing plate 16, and the trigger may drive the other end of the opening/closing plate 16 to be separated from the housing 11, thereby improving the dust removal efficiency of the dust collecting container 1. For example, as shown in fig. 5, the opening/closing plate 16 is provided at the bottom of the housing 11, the front end of the opening/closing plate 16 is pivotally connected to the housing 11, and the rear end of the opening/closing plate 16 is snap-fitted to the housing 11. When dust removal of the dust collection container 1 is not required, the rear end of the opening-closing plate 16 is snap-fitted with the housing 11 to close the dust collection chamber 11 a. When the dust collecting container 1 is to be dedusted, the trigger member can be triggered by pressing the trigger member, so that the rear end of the opening and closing plate 16 can be driven to be separated from the housing 11, the dust outlet 11e is opened, and the dust in the dust collecting chamber 11a can fall from the dust collecting chamber 11a under the action of gravity, which is convenient for operation.

In a specific example of the present invention, the platen 13 may be reciprocally moved in the up-down direction, and the initial position of the platen 13 is located above the ash pressing position. The pressing plate 13 includes a plate body 131, a first stopping member 132 extending in the up-down direction is disposed at the bottom of the plate body 131, a second stopping member 161 extending in the up-down direction is disposed at the top of the opening/closing plate 16, and the first stopping member 132 and the second stopping member 161 are disposed opposite to each other in the up-down direction. An elastic member 15 is provided between the pressing plate 13 and the opening/closing plate 16, and the elastic member 15 is a spring. The upper end of the elastic element 15 is sleeved on the first stopping element 132 and is in interference fit with the first stopping element 132, and the lower end of the elastic element 15 is sleeved on the second stopping element 161 and is in clearance fit with the second stopping element 161. When the dust collecting container 1 is subjected to dust removal, one end of the opening/closing plate 16 is separated from the housing 11, and the elastic member 15 is separated from the second stopper 161. From this, through above-mentioned setting, can make the cooperation mode between elastic component 15 and clamp plate 13 and the switching board 16 simpler, first only support piece 132 and second only support piece 161 and the cooperation of elastic component 15 respectively can play spacing effect to elastic component 15 in addition, can prevent that elastic component 15 from taking place the drunkenness, can play better effect that resets.

That is, the guide protrusions 171 and the guide grooves 131a may be provided on the inner peripheral wall of the dust collection chamber 11a and the pressure plate 13, or the guide grooves 131a and the guide protrusions 171 may be provided on the inner peripheral wall of the dust collection chamber 11a and the pressure plate 13, respectively. Therefore, the guide protrusion 171 can guide the pressure plate 13 by cooperating with the guide groove 131a, and the operation of the pressure plate 13 can be more stable.

In the specific example shown in fig. 15, the dust collection container 1 may further include a dust collection part 17, the dust collection part 17 is formed in a frame structure with an open top, and the dust collection part 17 may define the dust collection chamber 11 a. Wherein, the inner peripheral wall of the dust collecting part 17 is provided with a plurality of guide protrusions 171 spaced apart in the circumferential direction thereof, and each guide protrusion 171 extends in the up-down direction. The platen 13 is capable of reciprocating in the vertical direction, and the outer peripheral wall of the platen 13 is provided with a plurality of guide grooves 131a spaced apart in the circumferential direction thereof. When the pressing plate 13 is engaged with the dust collecting part 17, the outer circumferential wall of the pressing plate 13 is slidably engaged with the inner circumferential wall of the dust collecting part 17, wherein the plurality of guide protrusions 171 are engaged with the plurality of guide grooves 131a in a one-to-one correspondence and extend into the corresponding guide grooves 131 a. Therefore, through the arrangement, the matching structure between the pressing plate 13 and the dust collecting part 17 can be firmer, and the running stability of the pressing plate 13 can be improved.

It will be appreciated that when the filter assembly 12 filters the airflow, the filtered dust is highly likely to be adsorbed on the inner circumferential wall of the dust collecting chamber 11 a. When the pressing plate 13 is moving, the flexible member 133 can clean the inner peripheral wall of the dust collection chamber 11a, thereby cleaning up the dust on the inner peripheral wall of the dust collection chamber 11 a. Alternatively, the flexible member 133 may be a brush, a cloth strip, a sponge, or the like.

Specifically, the sponge 122 is placed on the bracket, and the hpa 123 is placed on the sponge 122, so that the air flow can sequentially flow through the sponge 122 and the hpa 123 to filter the air flow, and the hpa 123 is placed at the downstream of the sponge 122, so that the sponge 122 can be used for filtering dust with larger particles, and then the hpa 123 can be used for filtering dust with smaller particles, thereby improving the cleaning effect of the filter assembly 12 and prolonging the service life of the hpa 123.

Therefore, through the arrangement, the structural design of the filter assembly 12 can be simpler, and the combined use of the sponge 122 and the HEPA 123 can also improve the filtering efficiency of the filter assembly 12. The support frame 121 can play a supporting role for the filter component 12, and can prevent the filter component 12 from deforming under the action of air flow, thereby playing a better filtering effect. It will be appreciated, of course, that the filter assembly 12 may have other configurations, such as a filter screen, so long as the air is filtered to remove dust and the like from the air.
